Special considerations are necessary to contemplate any surgical procedure during pregnancy. Dermatologic surgeons must consider the best approach in order to minimize risks and provide optimal care to the mother and fetus. Nonemergency treatments should be postponed until after childbirth. When surgery is required, it is prudent to apply techniques and drugs that are well documented in the specialized literature.

Introduction: The use of topical anesthetics, has increased in recent years.While they are undoubtedly useful when recommended appropriately by a dermatologist, the improper use of topical anesthetics may result in complications, mainly due to inadequately applying them to wounded or inflamed skin; use on large areas of the body or mucus membranes; or use by high-risk patients. Adverse reactions can include transient local effects, allergic and/or irritative reactions, or more severe (though rare) effects, such as methemoglobinemia, arrhythmias, and cardiorespiratory failure. This paper discusses the commercial formulations of topical anesthetics currently available, their history, pharmacology, clinical use, and potential side effects.

The treatment of extensive, recurrent and poorly delimited basocellular carcinomas, located in highrisk areas of the body in patients with several comorbidities, is a challenge for the dermatologic surgeon. Mohs micrographic surgery is usually employed in such cases, presenting the risks inherent to large surgeries, in addition to the difficulties of closing the operative wound – which very frequently extends beyond the clinical limits of the lesion. In this paper, we report the use of photodynamic therapy prior to Mohs micrographic surgery in a 90-year-old diabetic and hypertensive female patient, with the objective of reducing and better delimiting the lesion for the subsequent exeresis.

Over the last 20 years, a number of methods have been used for facial rejuvenation; there is currently a search for new technologies that can overcome flaws inherent in the procedure. With the fractioning of the CO2 laser, the technique has gained renewed prominence. Nevertheless, the expectation of an improved procedure that is as effective as traditional ablative resurfacing and 100% safe has not been met. Although fractional ablative resurfacing has proven to be a considerably valuable procedure, results do not match those of the traditional procedure. And while the fractioning of the laser decreases side effects, they must not be overlooked. In this article we describe in detail our personal experience, including possible side effects and how to avoid and treat them.
